Process Control Serial Communication Solution – Emerson KJ3241X1-BA1 | DeltaV Series
Where This Product Is Used
The Emerson KJ3241X1-BA1 (Part No. 12P2506X062) Redundant Serial Interface Card is a critical communication module within the Emerson DeltaV Distributed Control System (DCS). It is deployed across high-availability process industries where serial device integration and redundant communication paths are non-negotiable.
Typical application environments include:
- Oil & Gas: Upstream wellhead controllers, midstream pipeline SCADA, and downstream refinery DCS networks requiring uninterrupted serial communication with field devices.
- Power Generation: Turbine control systems, boiler management units, and substation automation where RS-485 serial loops connect legacy instrumentation to modern DCS infrastructure.
- Chemical & Petrochemical Plants: Continuous process control loops integrating HART-enabled transmitters, valve positioners, and analyzers via serial backplane communication.
- Pulp & Paper / Water Treatment: Multi-drop serial networks linking PLCs, drives, and smart field devices to the DeltaV controller chassis.
- Pharmaceutical Manufacturing: FDA-regulated batch processes requiring validated, redundant I/O communication paths for 21 CFR Part 11 compliance environments.

Application-Specific FAQ
Q: Is the KJ3241X1-BA1 compatible with all DeltaV controller versions?
A: It is designed for DeltaV MD, MQ, and SD series controllers. Compatibility with specific firmware versions should be verified against Emerson’s DeltaV Hardware Reference Manual. Contact us if you need version-specific confirmation.
Q: Can this card be used in a non-redundant (simplex) configuration?
A: Yes. While the KJ3241X1-BA1 supports redundant pairing, it can operate in simplex mode as a single serial interface card within the DeltaV carrier.
Q: What serial protocols does this card support?
A: The card supports RS-485 serial communication. HART pass-through capability depends on the connected field device and DeltaV configuration. Consult Emerson’s product bulletin for protocol-specific details.
Q: Do you provide warranty on refurbished units?
A: Yes. Konmask offers a 90-day functional warranty on all tested/refurbished modules. New surplus units carry the original manufacturer warranty where applicable.
Q: Can you assist with DeltaV system integration or commissioning?
A: We specialize in parts supply and sourcing. For system integration services, we can refer you to certified Emerson system integrators in your region.
